Clamps of this type hold the work piece using a straight-line or pushpull, Toggle clamping action. These clamps come with a wide range of holding capacities from 45kg to about 5000 Kgs. The easy to operate push pull handle moves the plungers of the clamp in and out along its axis. Most of these clamps can be locked in two positions, and hence can be used as either push or pull clamps.
